Wya better than the plastic ones. Love this product. Opening up oxygen tanks for patients is a lot easier now.

This iGuerburn oxygen cylinder tank wrench is a handy tool to have when working with compatible gas cylinders and equipment. The small size makes it easy to store in a toolbox or equipment bag, while the heavy-duty metal construction gives it a solid and durable feel. The wrench fits well, provides good grip, and makes opening and tightening cylinder valves much easier than trying to use improvised tools. The design is simple, practical, and built for repeated use. Overall, I’m impressed with the quality and convenience of this wrench. It’s a great addition for anyone who needs a reliable cylinder valve tool and wants something compact that will last. Excellent value for the price and I would recommend it.

My granddaughter needed these for her EMT shifts. She said she loved them.

I was given a plastic one with the rental of my oxygen tank, I felt like I was going to break it with every use….So glad I bought this heavy duty metal one! I feel more in control and safer using this one to open and close the valve.

This is a backpack for my husband’s oxygen portable cylinder. We were pleased with the design, weight and quality.
